Abstract

Un système d'analyse selon un mode de réalisation effectue une analyse concernant un dispositif de transport qui transporte des articles. Le système d'analyse est pourvu d'une unité de traitement. L'unité de traitement classifie l'état de fonctionnement du dispositif de transport à l'aide d'un premier signal transmis à partir d'un premier détecteur qui détecte le mouvement du dispositif de transport et d'un second signal transmis à partir d'un second détecteur qui détecte la présence ou l'absence d'un article sur le dispositif de transport.
